Maria Asenina of Bulgaria
Maria Asenina (born between 1238 and 1241) was a Bulgarian princess, daughter of Emperor Ivan Asen II and his third wife Irene Komnene Doukaina. She was the full sister of Emperor Michael Asen.
Bulgarian historiography traditionally identifies her as the wife of Emperor Mitso Asen, who ruled in 1256–1257, making her briefly empress consort. On that view she was the mother of Emperor Ivan Asen III and ancestress of the Byzantine branch of the Asen dynasty.
